Public bug reported:

Refer to https://github.com/aws/aws-sdk-cpp/issues/1253

I found HTTP request issue when I was testing my application which does long 
polling a certain REST API for every 100ms and after some duration of time, CPU 
spikes up to 100% because of curl.
For the clear test, I made simple HTTP request application which is in the link 
above and ran it with curl 7.58 and curl 7.66 the latest.
The sample application also shown same problem with curl 7.58 but worked fine 
with curl 7.66 the latest.
This test has done with Docker Ubuntu 18.04 LTS and Ubuntu 18.04 LTS in WSL.
